Hello all! I have a 503cx with an A12 magazine. Since I have read that the darkslide, with prolonged usage, can slowly damage the light trap, I was wondering if I could load and retrieve the film without using it. I would keep the camera cocked and load and retrieve the film while the magazine is attached to the camera. I would detach only the film holder inside the magazine. Is this possible? I have not tried it yet because I fear damaging the camera. I faithfully await for your advice. Thank you very much and please forgive me for my bad English: I am not a native speaker.
